straw-colored at maturity, papery in texture, more or less inflated, 

 smooth, nerved, tapering into a beak as long or longer than the body : 

 spikes few to many, distinct, compactly flowered : stigmas mostly 

 three. — The representative species of the section are the larger 

 members of the Vesicaria?, and Lupulinte. The extreme is represented 

 on the one hand by tlie monostachyous C microglochin and G. pauci- 

 jiora, and on the other by the comose and green-spiked C Pseudo- 

 Cyperus. But even with these widely dissimilar extremes the section 

 is a natural one. There are complete and almost insensible grada- 

 tions from the one limit to the other. Most of the Lupulinas and 

 the extreme species of the Pseudo-Cyperse do not have straw-colored 

 perigynia until full or over maturity, while the perigynia of the 

 Pauciflora3 and Pseudo-CyperEe are scarcely inflated or papery in 

 texture. Occasionally the nerves are indistinct, rarely wanting. C 

 Grayii alone has hispid perigynia, and that rarely. The species of this 

 section, almost entirely North American and European, are mostly 

 large and stout, and probably to be regarded as the most developed 

 of the genus.

 Orthocerates, Koch, Fl. Germ. 748, is a sectional name made for V. microglo- 

 chin.) Perig3nium greenish, linear-lanceolate or ahiiost needle-shaped, not 

 inflated, strongly deflexed at maturity, several times longer than the incon- 

 spicuous scale : spike androgynous, the pistillate flowers at the base, few. — 

 Small species, rare or local.

 Remarkable for the elongated rhacheola which projects from the 

 perigynium, completely filling the orifice. This plant stands midway 

 between Carex and the singular genus Uncinia. — Colorado, Hall &
